(Kennebunkport, ME) -- Former President George H.W. Bush is safely back on the ground after a birthday skydive. He made a tandem jump from a helicopter hovering over Kennebunkport, Maine. He had a free fall of about ten seconds before a red, white and blue parachute opened and he glided to the ground. Today's the former president's 90th birthday. Earlier today, he tweeted "It's a wonderful day in Maine -- in fact, nice enough for a parachute jump."
